A Norwegian passenger plane bound for Barcelona issued a warning alarm after taking off from Arlanda Airport and receiving indications of a technical fault after departure.
They have turned back and made a normal landing at Arlanda, says Carl Mossberg, press spokesperson at Swedavia, to TT at 22:00 on Thursday evening.
According to Expressen, it is a Boeing 737-8JP model plane. 188 people are on board.
It's a hydraulic system that has failed, it's not dangerous, says Sarah Neergaard, acting press officer at Norwegian to TV4 News.
